Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Projectile Motion | Brilliant Math & Science Wiki

When first getting a grip on classical mechanics, it is important to digest certain formative examples. One of these examples is that of a projectile: an object that is subject only to the force of gravity. A surprising number of common physical scenarios can be closely modeled with this premise. Since it is only subject to gravity, the projectile cannot be in contact with any surface.
